Engine

Currently the best powerplant that can be installed in a Bonanza is the Continental IO-550-R overhead induction engine. With superior reliability, service life, performance, and minimal vibration, the IO-550-R outdoes all other piston options. RPM/MAP restrictions are eliminated, and turbine smoothness is felt throughout the operating range. The STC’d conversion kit from Tru Atlantic incorporates a two piece carbon fiber nosebowl and cowl doors which decrease weight and improve fitment. The kit also includes a rugged, tight sealing baffle setup to increase cooling ability, and all parts are FAA/PMA approved.
